In depth 3D Printing and Additive Manufacturing

Our goals are your goals: better parts, safer materials, lower costs

3Dresyns develops practical, cost-effective solutions for 3D printing and Additive Manufacturing (AM). Our focus is simple: help you produce better, safer and more sustainable materials and processes, while keeping total cost and environmental impact as low as possible.

3Dresyns offers a full range of safe, functional materials—from durable, tough and elastic resins to sacrificial materials for Direct and Indirect Additive Manufacturing.

We also develop biodegradable and durable biocompatible materials based on renewable and safe raw materials.

Our biocompatible resins are designed for safer handling and safer final use. Many of our safest grades are monomer-free, reducing the risk of monomer migration and improving user safety.

Direct vs Indirect Additive Manufacturing (AM)

In practice, AM can be approached in two main ways: Direct AM (printing the final part directly) and Indirect AM (printing tools/models/molds to manufacture the final part).

Direct AM

Direct AM is ideal for fast iteration and short-run production. With SLA, DLP, LCD and Inkjet printing, you can produce high-resolution polymer parts, including functional composites (resins filled with additives, powders or functional phases).

Material Process Output Benefits Limitations
3D resins Direct AM 3D resin parts (optionally filled with functional additives, ceramics, metals, polymers, or exotic materials) Cost-effective direct production for prototypes and short runs Typically less cost-effective for high volumes vs conventional molding/injection
Direct printing of sintering ceramics, metals, polymers & exotic materials Print + debind + sinter Sintered ceramics/metals/polymers/exotic materials Direct route to sintered parts (short runs) Higher equipment cost, complex tuning, slower debinding, and thickness limitations can apply

 

Indirect AM (two-step manufacturing)

Indirect AM uses 3D printed models or molds (durable or sacrificial) to produce the final part by injection or casting. This approach is often preferred when you need better final material properties, lower material costs, or access to established conventional materials and certifications.

  • 3D print molds with SLA, DLP, LCD or Inkjet
  • Inject or cast resins, plastics, ceramics, metals, polymers, or exotic materials

Types of molds

Indirect AM of ceramics, metals, polymers & exotic materials (CIM / MIM / PIM)

The injection of Powder Injection Molding (PIM) feedstocks (including ceramic and metal, polymers (such as polyimide) and exotic materials) into 3D printed durable or sacrificial molds offers key advantages versus direct printing of highly powder-loaded resins.

Why this route wins for many ceramic/metal applications

  • No thickness limitation (vs 1–3 mm typical in direct ceramic/metal SLA printing)
  • Lower risk of micro-cracking during debinding
  • Faster, cleaner debinding and sintering cycles
  • Higher final density and lower microporosity
  • Improved isotropy and repeatability
  • Access to the full range of conventional technical feedstocks
  • Lower total cost using affordable printers for molds

3Dresyns solutions for Indirect AM

Solution Link Typical use

Sacrificial molds Soluble & removable sacrificial 3D resins Complex or intertwined geometries
Ceramic & metal feedstocks CIM & MIM slurries Injection molding + debinding + sintering
Polymer & exotic feedstocks PIM feedstocks High-performance polymer & composite parts

 

Typical equipment ranges (guidance)

  • SLA / DLP / LCD printers for molds: 200 – 2,000 €
  • Manual injection (micro syringes / small units): <50 € – 3,000 €
  • Automatic injection machines: 3,000 – 7,000 €+
  • Debinding & sintering furnace (material-dependent)

Optional: Direct AM of functional plastics with SLA (high-resolution)

Direct SLA/DLP/LCD printing is a strong option for functional plastics and prototypes, especially when speed and resolution matter. 3Dresyns offers safe functional engineering resins tailored to demanding applications.

Key takeaway

Use Direct AM when you need speed, iteration, and short-run printing. Use Indirect AM when you need the best final material performance, scalability, and access to conventional high-performance materials.
